PEA-HARVESTING MACHINE.

Specification of Letters Patent.

Patented June 19, 191 7.

Application filed January 25, 1916, Serial No. 74,148. Renewed May 18,1917. Serial No. 169 ,575.

' To all whom it mm concern:

- is a specification.

My invention relates to' a pea harvester of that type characterized by aconstruction so arranged that the harvester may be run over the vinesand will free the pods from the vine and the peas from the pods.

One object of the present invention resides in the provision of meansfor adjusting the effective height of the pea vine re-' celvlng means,whereby the machine may be easily adapted for vines of differentheights.

A further object consists in providing novel means for removing the podsfrom the vines and freeing the peas from the pods.

A still further object resides in the. provision of simple and effectivemeans for separating the peas and broken pods, and conveying the formerto a suitable storage compartment.

And a final object consists in so arranging the structure hereinbeforeoutlined that all the moving parts thereof, except the adjustable peavine receiving means, are operated from the wheel structure of theharvester.

With the above and other objects in View, I will now proceed to describea specific embodiment of my invention as illustrated in the accompanyingdrawing, wherein:

Figure 1 is a view of the pea harvester, in side elevation.

Fig. 2 is a View in front elevation.

Fig; 3 is a top plan view; and

Figs. 4 and 5 are views, showing respectively in plan View and in sideelevation, the construction of flexible jointed heaters or flails.

In detail:

The pea harvester comprises the axles 1 and 2 carrying wheels 3 and a,respectively. Supported by the axles 1 and 2 are the bottom framemembers 5 and 6 which, in turn, carry the weight of the upper framemember 9 supported from said first mentioned frame members by means ofthe vertical stays 8. At the top of the harvester is a transversallyextending member 9 in which is journaled one end of a spindle 10provided with a handwheel 11. The other end of said spindle '10 isthreaded into a second transverse member 13. The top member 7 issupported by the vertical stays 8 and carries at its extreme sides, thevertical members 14; said members 14 carry, at their lower ends, the peavine receivingv means which consists of the two opposing members 15 and16, shaped on their adjacent ends in such a manner as to properly guidethe vine through the machine. The members 15 and 16, by reason of thearrangement of spindle 10, may be raised or lowered as required.Journaled in a bearing 17 carried by member 13 and also in a bearing 18car ried by member 9' is a vertical shaft 19 carrying at its upper end abevel gear 20 and at its lower end a bevel pinion 21, the latter meshingwith a bevel gear 22 on axle 1; while the former meshes with a bevelpinion 23 on a transverse shaft 24 mounted in bearings 25 and 26.

The said shaft 2e carries a sprocket 27 over which a chain 28 runs, saidchain engaging a smaller sprocket 29 on a shaft 30 journaled in supports30 and provided with bevel gears 31 and 32 which mesh with bevel gears33 and 34: on shafts 35 and 36 carrying drums 37 and 38, said shaftsbeing journaled in bearings 39.

The drums 37 and 38 carry flexible ointed beaters or flails 40 which arecomposed of a series of links 41 and are so constructed that they standout laterally and yet are flexible laterally. The arrangement andsetting of the drums 37 and 38 are such that the fiails 41, when thedrums revolve, intermesh and exert a rubbing action against the vinewhich not only removes the pods but ruptures the latter to free thepeas.

The peas and pods thus freed of the vine drop on to the shaking screens42. These screens have saw teeth projections as 43 on top, which withthe assistance of the shaking screens will carry the empty pods andstalks which have been broken off, to the rear of the screens as at 46and fall on the ground.

The screens 42 are sloped with the lower ends toward the wheels. Theseends form compartments such as 4:7 which are made deeper than the innerpart of the screen and have the bottoms shaped in saw tooth form such as48. The compartments 47 are continued beyond the ends of the screen 42and as the peas have now Worked their way into these sections they areled into the conveyers 48 by means of a chute as 49.

The conveyers are driven through the medium of a shaft 50 connected by agear 51 to a gear 52 on a shaft 24.

The shaking or oscillating motion of the screens 42 is obtained by meansof a cam or eccentric arrangement on the shaft 53 which in turn isdriven from the shaft 50 by means of the belt forming the inner part ofthe conveyer.

The peas after being carried up the con.- veyer are led into sacks orthe like.

WVhile in the foregoing specification, I have described a specificembodiment of the present invention, it is nevertheless to be understoodthat, in practice, I may resort to such practical modifications as fallWithin the scope of the invention as defined in the appended claims. 1

I claim:

1. In a harvester, threshing means to remove ,a product from a plant,such means including drums, and flails laterally extending from saiddrums and flexible only in a horizontal plane.

2. In a harvester, threshing means, including vertically disposed drumsrotatable in opposite directions and laterally extending flails flexibleonly in a horizontal plane, said fiails intermeshing as said drums arerotated. 1

3. In a harvester, threshing means to remove a product from a plant,such means including vertically disposed drums rotatable in oppositedirections and means to guide the plant between said drums, fiailsextending from said drums and retained. in a horizontal plane andflexible only in a horizontal plane.

In testimony whereof I have hereuntoset my hand in the presence of twosubscribing Witnesses.
